Bucket for a bucket elevator

Abstract

A bucket and a corresponding bucket elevator, the bucket has a bucket wall surrounding a filling and discharge opening and having a rear wall and a front bucket wall, the front bucket wall having a front edge delimiting the filling and discharge opening, and the bucket being connectable to a conveyor device via the rear wall, wherein the ratio between the bucket depth, which corresponds to the horizontal distance between the rear wall and the front edge, and the bucket height, which corresponds to the vertical distance between a bucket low point and the front edge, is greater than 1, preferably greater than 1.3, more preferably greater than 1.5.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to European Patent Application No. 20193745.5 filed Aug. 31, 2020 as incorporated herein in its entirety.BACKGROUND OF THE INVENTIONTechnical Field[0002]The invention is based on a bucket for a bucket elevator, which has a bucket wall surrounding a filling and discharge opening, which comprises a rear wall and a front bucket wall, the front bucket wall having a front edge delimiting the filling and discharge opening, and the bucket being connectable to a conveyor device via the rear wall. The invention further relates to a corresponding bucket elevator.Discussion[0003]EP 2 870 084 B1 describes a belt bucket elevator with a driven belt and a plurality of buckets for conveying bulk material. The buckets have a smaller width at their bottom than at the upper end of their sidewalls, which are thereby laterally outwardly flared. At the lower end of their rear wall facing the belt, the buckets also have a project...

AI Technical Summary

Benefits of technology

The invention provides a bucket with improved ejection behavior. The flat bucket shape allows for low centrifugal force to effectively eject material, even at low conveying speeds. The front edge of the bucket prevents premature ejection of bulk material from the bucket. The filling and discharge opening can be limited by an edge surrounding and closing the bucket. The bucket low point is determined by the lowest point of the bucket in the vertical direction. The tethering device fixes the bucket to the conveyor device and prevents material from penetrating between the conveyor device and the back of the bucket. The flat angle of inclination and the inclined section of the rear wall serve to direct material exiting the bucket along a direction away from the conveyor. The inclined upper edges increase the filling volume of the bucket and favor or prevent the escape of material at the front of the bucket.

Problems solved by technology

The filling and discharge opening can be limited in particular by an edge surrounding and closing the bucket wall.
